From Natural Discovery to AI‐Guided Design: A Curated Collection of Compact Enhancers for Crop Engineering

open access: yesAdvanced Science, EarlyView.
ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...

OCTN2 Activates a Non‐Canonical Carnitine Metabolic Pathway to Promote MASH‐HCC Progression and Immunotherapy Resistance

open access: yesAdvanced Science, EarlyView.
In non‐MASH‐HCC, L‐carnitine promotes tumor progression primarily through its classical role in enhancing fatty acid oxidation (FAO). However, in MASH‐HCC, where FAO is markedly suppressed, L‐carnitine shifts from this canonical function to serve instead as an intracellular acetyl group buffer.

IgG‐Bridging–Seeded Synergistic Aggregation of SARS‐CoV‐2 Spikes Underlies Potent Neutralization by a Low‐Affinity Antibody

open access: yesAdvanced Science, EarlyView.
Low‐affinity antibodies are frequently disregarded in discovery pipelines. This work reports P5‐1C8, a Class 1 SARS‐CoV‐2 antibody with weak trimer binding (KD‐to‐IC50 > 3700‐fold) yet potent neutralization of Omicron JN.1. Structural, biophysical, functional, and coarse‐grained simulations collectively demonstrate that transient inter‐spike IgG ...

Bioluminescence: the First 3000 Years (Review) [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2008
Bioluminescence is defined as the emission of light from a living organism that performs some biological function. Bioluminescence is one of the oldest fields of scientific study, dating from the first written records of the ancient Greeks.

A Simplified Three‐Tailed N‐Alkyl Phosphoramidate Lipid Platform Enables Inguinal Adipose‐Accumulated mRNA Delivery for Anti‐Obesity Therapy

open access: yesAdvanced Science, EarlyView.
This study develops an mRNA therapy encoding a long‐acting GLP‐1/FGF21 fusion protein. A three‐tailed ionizable lipid engineered three‐component lipid nanoparticle delivers the mRNA to inguinal adipose tissue. In obese mice, this targeted, dual‐hormone treatment potently reduces body weight, fat mass, presenting a localized strategy for metabolic ...

An Overview of Aquatica Fu et al., a Phylogeny of Aquatic Fireflies Using Mitochondrial Genomes, a Description of Two New Species, and a New Record of Aquatic Fireflies in China (Coleoptera: Lampyridae: Luciolinae)

open access: yesInsects
There are now seven species in the genus Aquatica Fu & Ballantyne, with all but one known from the characteristics of males, females, and larvae. Molecular information is combined with morphological taxonomy for the delimitation of both genus and species.

Synergistic Mn‐MOF Activation of Pistol Ribozymes for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A Mn2+‐based metal–organic framework delivers a catalytic Pistol ribozyme for targeted PD‐L1 mRNA cleavage in tumor cells, with the released Mn2+ not only inducing immune activation in immune cells but also increasing the Pistol ribozyme catalytic activity.

Engineered Small Extracellular Vesicles Targeting Tumor‐Associated Endothelial Cells to Effectively Remodel the Glioma Microenvironment

open access: yesAdvanced Science, EarlyView.
This study developed a novel drug delivery platform that overcomes the blood‐brain barrier in glioblastoma. By fusing IGFBP7 with small extracellular vesicles, the platform specifically targets tumor vasculature. It effectively delivers temozolomide, suppressing tumor growth at low doses.

m1A‐Dependent TRMT6/61A‐ARG2 Axis Drives Protumorigenic Senescence by Remodeling the Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
Uncovering a new layer of translational control, this study reveals how TRMT6/TRMT61A‐mediated tRNA‐m1A methylation drives pro‐tumorigenic senescence in colorectal cancer. By selectively enhancing ARG2 translation, this epitranscriptomic axis triggers an NF‐κB‐dependent SASP.
